Spotlight on the Gulf Coast Conference - Analytical Instrumentation New guide outlines techniques to measure viscosity of in-service oil
The ASTM committee on petroleum products, liquid fuels, and lubricants (D02) has created a new standard (D8185) that will serve as a guide for determining how to measure viscosity of in-service oil.
According to committee members, anyone with a technical background in lubrication or condition monitoring can use this guide to determine options for viscosity testing.
Generally, proper lubrication is important for maximizing the usable life of a machine or device. Viscosity can affect the energy and mass transfer of the lubricant in the machine.
“If the viscosity is too high, it might exceed the pumping capabilities, and lubricant may not be able to reach critical components,” says ASTM International member Norm Kanar, marketing and sales manager at Savant Labs. “If viscosity is too low, the lubricant may not be able to protect the machine from premature wear of components.”
Kanar notes that the new standard contains practical, historical, and relevant information on how to measure in-service lubricant viscosity. The guide also provides workers with basic principles of each measurement approach and how to conduct them.
New standard supports alternative “blendstock” fuel

47011pr@reply-direct.com TE Instruments Presents the XPERT in
TOC and TNb analysis of (waste) waters Monitoring the amount of organic substances in (waste) water is important in most industrial plants for several reasons. The discharge of water is regulated stringently by environmental protection agencies. Substances of organic matter which are present in these effl uents are potentially harmful. In many cases, sum parameters of Total Organic Carbon (TOC) and Total bound Nitrogen (TNb) are required to be analyzed. These parameters are also monitored during process control to ensure the removal of organic matter has been successful.
TE Instruments’ XPERT-TOC/TNbanalyzer is the perfect solution to cover these applications simultaneously, fully compliant with international test methods like EN 1484and ISO 8245.
Experience counts!
Decades of experience have been deployed to create this new analyzer which represents the ultimate combination of robustness, accurate sample analysis and user convenience. The XPERTenables its users to analyze Total Organic Carbon (TOC) and Total bound Nitrogen (TNb) simultaneously, within a few minutes, from a single injection.
Fully equipped: all-in-one Footprint
TE Instruments designed the XPERT in a unique way, integrating both detectors and liquids auto sampler into the footprint of the analyzer.
The liquids auto sampler and stirrer function for all sample positions are by default included. Particle-containing (waste)water samples (<0.8 mm) are automatically homogenized, picked-up and measured. No additional options or modifi cations required.
The ASTM committee on petroleum products, liquid fuels, and lubricants (D02) has approved a new standard for a renewable bio-based blendstock that can be used as a diesel alternative. The standard (D8181) covers specifi cations for microemulsion blendstock for middle distillate fuels.
“This new standard is needed because there is no relevant existing standard for this type of chemistry,” says Kristin Aramthanapon, technical advisor at Sylvatex, Inc. She adds that these specifi cations will be used by manufacturers and customers to ensure that the material being produced and used meets quality and consistency measures while also correlating with vehicle performance to fuel properties.

The integrated auto sampler injects the sample directly into the septum-less introduction port. While sampling, none of the valves contacts the actual sample at any given time, eliminating any potential carry-over. Funnel-Tec™ transfers the complete sample to the hot zone of the furnace, minimizing memory effect.
The ProCAT™ combustion tube guarantees optimal temperature distribution and protects the catalyst at the same time. This results in an extended lifespan of the catalyst material, complete sample oxidation, and extremely accurate results.
